AXLE-LUBRICATOR.

Specifcaton of Letters Patent.

Patentecl Mar. 29, 1921.

Application filed March 5, 1920. Serial No. :363,377.

'To all whom izi may concem:

Be it known that I, HONEYMAN B. FOL- sn'rrnn, a citizen of the Dominion of Canada, residing at Vanconver, in the Province of British Columbia, Canada, have invented certain new and useful Inprovements n Axle-Lubricators, of which the following 1S a specification.

This invention relates to a means for applying a hard grease as a lubricant to the axle hearing of a railway Vehicle. Usually these bearingsnre lubricated by means of oiloaked waste packed within the axle box in contact with the supporting end of the axle.

It is to apply lubrication by n'eans of hard grease instead of oil in an existing aide box, that the invention which is the subject ot this application has been devised The inventicn is particularly described in the :following specification, reference being made to the drawings by which it is accornpanied, in which: r

Figure l is a section through the axle box on the line l-l in Fig. 2 showing the grease lubricating device in elevaton, and

F 2 is a Vertical cross section on the line 2-2 in Fig. 1. i

In these drawings 2 represents the aXle end of a railway vehicle and 3 the axle box within which is the hearing 4, which sustains the load on the axle. To the under side oi' the axle 2 is applied a block 5 of hard grense which is retaned in position by a sheet metal casing G conforming generally to the dimension of the grease block and the upper edge of it fitting against the curvatui-e of the axle end 2.

The length of this block of grease and its cnsing 6 is somewhat less than the length ot the axle end 2 between its shoulders, so as to per-mit of the dcsired limited endwise mwement of the aXle.

The block of ;gi 'ease 5 is held up against the underside of the aXle by a presser plate i' on which it rests, which plate is provided on one' side with a steni 8 which projects through a slctted aperture 9 in one side of the casing and is mounted in a hearing 9', pivotally mounted to turn on a vertical axis in the end of an arin 10 mounted free on a pin ll which extends across the 'front of the aXle boX %i and is supported in its side walls. The arin 10 has a projection 12 adjacent the pin 11 by which the movement of the grcase supporting end of the arm is limited toward the axle, and around the red a spring 13 is coiled, the ends of which bear at 14 on the' axle box and at 15 on the arni 10.

The block oi' grease 5 is thus held by the presser plate 7, arin 10 and spring 13 in lubricatin g contact with the underside of the axle ende 2 in a nanner that it may adapt itself to the movement of the axle in the axle box, and is retained against lateral displacenent by the casing 6 to which the grease block 5 is connected by pins 16 which pass through the sides of the casing and through the grease.

Having now particularly described my in- Vention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

1. Means for lubricating a railway axle with hard grease., said means comprsng the conbination with the axle box and its bearing on the aXle, of a block o'l' hard grease, a container for the block ot grease, means securing the container to the block of grease and a resilient means for holding the block of grease and the container withthe grease in contact with the axle.

2. Means folubricating a railway aXle with hard grease, said means comprisng the con'bination with the aXle box and its hearing on the axle, a block of hard grease applied to the undersidc ot' the axle, a substantially rectangular TEUHG of thin metal inclosing the sides and ends of the grease block, means for connecting the grease to the casing a 'gresser plate freely fitting the casing and applied to the underside oi? the gri-ease, and'means tor applying a resilient npward pressure to the plate.

3. Means 'for lubricating a railway aide with hard grease said means comprisng a substantially rectangular treme extendine; approxiinately the length ot the axlc hearing and adapted to receive a correspondingly sha ed block ot? hard grease with provision for retaining; the grease in the frane a presser plate freely fitting the frane, said plate having),` a pin projecting horiaontally froni one side adjaccnt its nidlength, a lever mouited on a pin attending horizontally across the front of the ajde box, a spring between the axle box and the lover tending to .move the lever Upward, and means con necting the :free end of the level' to the pin of the presser plate and allowin horizontal and Vertical movement in such connection.

In testimony whereo'l I zifti): my signature.
